DC Application Varistor Design Guide

When designing electronics for lower DC voltage automotive applications, it’s vital to protect against the damaging effects of high voltage transients.

To meet this demand, high surge current varistors should be the focus of your circuit protection strategy. Varistors are voltage-dependent, nonlinear devices that absorb the potentially destructive energy of the incoming transient pulse and protect vulnerable circuit components—enhancing the safety and reliability of your automotive system.

Need advice on transient suppression techniques? Want help choosing a reliable high surge current varistor for your next automotive design?
